Topic: Disappearing Mixer Input Channels 9-16 at 88.2/96kHz
I have an HDSP AES-32 PCIe card, which has been working fine at the lower sample rates.
However, I need to use it at 88.2kHz, and whenever I set the WC input to receive 88.2 clock (from Big Ben) or lock to AES/EBU (on channel 9, for instance)--the input source having come from either a Crane Song Spider's multichannel AES/EBU outputs or a Genex GX-A8 converter's AES-EBU outputs--everything looks fine UNTIL....
Until I actually open Pyramix *or* Sonar 8.5. As long as either application is set to go at 44.1kHz, the HDSP mixer window stays put, and the meters read appropriately on channels 9-16.
BUT if either Sonar or Pyramix opens in 88.2 or 96kHz (either set as default, or I instantiate a "new file" at the higher fs), the last eight channels on the top row of the HDSP Mixer promptly disappear, and the window looks a bit lopsided on top! Both Vista and Windows 7 are affected.
And, strangely, three of the channel inputs (from 9-16) show up on 6-7-8 now--which makes no sense, especially in the case when channels 1-8 were not being fed any digital input at all.
If I'm in Sonar, sometimes going to the Sound control panel and simply clicking on the "record" tab gets the higher channels back, but no input is subsequently passed through the mixer to the application, so "the damage has been done."
I was led to believe that I could have 16 channels of input and output at ALL sample rates, but this behavior seems to indicate that "double the sample rate, halve the number of input channels).
It does this with 3.08.2 and 3.08.3, in Vista and in Windows 7, as I said. I'm running these applications on a Boot Camped 8-core Mac Pro. I do not have a multi-channel Mac application (only Pro Tools, which requires different hardware..) to see if the same behavior obtains in Leopard or Snow Leopard, which are also possible operating systems on this "big Mac."
I am using ASIO, of course.
Must I recable my digital inputs, and be resigned to using only the first 8 channels at 88.2kHz? And/or sticking with 44.1kHz for projects over 8 channels?
I hope I'm doing something wrong!
